+#X text 232 380 splits a Dim[A... \, B] grid into Dim[B] vectors \,
+producing new Dim[B] vectors that each contain numbers from 0 to B-1
+indicating the ordering of the values. The result is a Dim[A... \,
+B] grid.;
+#X text 232 441 for example \, connecting a [#grade] to a [#outer ignore
+0] to a [#store] object \, storing a single vector into [#store] \,
+and sending the same vector to [#grade] \, will sort the values of
+the vector. however for higher-dimensional grids \, what should go
+between [#store] and [#grade] to achieve the same result would be more
+complex.;
+#X text 232 541 you may achieve different kinds of sorting by applying
+various filters before [#grade]. the possibilities are unlimited. if
+you plug [#grade] directly into another [#grade] \, you will get the
+inverse arrangement \, which allows to take the sorted values and make
+them unsorted in the original way. note that this is really not the
+same as just listing the values backwards.;
